I'm running the Yellow spring in the JP I just built.I've also got the low mass Hammer and it seem's to work well with both comm. .223 and Mil. spec.5.56 , Have'nt had any issues yet with light strikes but I have'nt shot alot thru it yet, maybe 100 rnd's of each ,lake city and federal . I would also recomend a JP adjustable Trigger with the Low mass hammer. I am amazed with the combination .Crisp, Clean stroke and a light 3 1/2 lb pull with virtually no take up or overtravel in the trigger pull , nor did I notice any stacking in the trigger pull like some cheaper springs tend to cause. JP hit the mark with this combo.
